Mechanical Performance of Jute and Basalt Fiber Geo-grid-Reinforced Epoxy Hybrid Composite Material

ABSTRACT

In the present work, the jute fiber and basalt fiber mats (geo-grid) reinforced with epoxy hybrid composite material were prepared in a laboratory by using hand layup technique. The influence of the stacking sequence on physico-mechanical properties of hybrid composite materials was experimentally investigated as per the ASTM standards. The moisture content in the hybrid composite was slightly on higher side as compared to the simple composite (six layers of jute). The tensile strength of the hybrid composite (two layers of jute) was enhanced by 20% as compared to the simple composite. It was observed that the hybrid composite shows high strain (4.5%) and large extension (13.5 mm) in the flexural test as compared to that of simple composite.

摘要

采用手工叠层技术，在实验室制备了黄麻纤维毡和玄武岩纤维毡（土工格栅），并用环氧树脂复合材料对其进行了增强处理.根据美国材料试验协会（ASTM）标准，对复合材料的堆积顺序对复合材料物理力学性能的影响进行了实验研究.与简单复合材料（6层黄麻）相比，混合复合材料的含水量略高.复合材料（两层黄麻）的拉伸强度比简单复合材料提高20%.结果表明，与单一复合材料相比，复合材料在弯曲试验中表现出高应变（4.5%）和大延伸（13.5 mm）.
